KEY-FASTENER;

Specification of Letters Patent. Pai entgd Na a 9 15m Application filedJanuary 13, 1915.

To all whom it may concern Be it known that 1, James F. POWELL, acitizen of the United States, residing at Flint, in the county ofGenesee and State of Michigan, hare invented new and useful Improvementsin Key-Fasteners, of which the following is a specification.

The invention relates to a key fastener, and has for its primary objectto provide a device of this character wherein on the inserting of thekey within the lock it can be fastened therein so as to preventsurreptitious removal of the key only from the side of the lock in whichthe same is inserted, thus making it impossible to manipulate the lockfrom the opposite side thereof when the key is engaged therein.

Another object of the invention is the provision of a key fastenerwherein the escutcheon plate for a look is of novel form so that the keyfor manipulating the lock can be readily fastened to the plate afterinserting the said key within the lock, thus preventing the loss of thekey as well as protecting the lock to avoid the use of a duplicate keyor a dummy for a surreptitious'entrance to an inclosure.

A further object of the invention is the provision of a key fastenerwherein the key is of novel form and can be readily and easily fastenedafter its insertion within a lock.

A still further object of the invention is the provision of a keyfastener which is simple in construction, reliable and etiicient in use,and inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanyingdrawing, andpointed out in the claim hereunto appended.

In the drawing z Figure l is a side elevation of a key fastenerconstructed in accordance with the invention. Fig. 2 is a fragmentaryedge elevation of a door showing the lock or escutcheon plate and thekey fastener constructed in accordance with the invention.

one of the escutcheon plates. Fig. 4.- is a side elevation of the key.Fig. is a detail View of the latch for the key.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates an elongated escutcheonplate, two of which are ordinarily used in connection with a door lock13, the latter being of the ordinary well-known construction, and thisescutcheon plate A is formed with the usual. keyhole C through which ispassed the key into the lock B for manipulating the same.

The key comprises a two-part shank 5, the

. parts of which are swingingly connected to each other through themedium of a hinged joint 6, and on one of these parts is the bit 7 foractuating the lock B, while the other part of the shank is formed withan elongated slot 8 for a purpose presently described.

The escutcheon plate A has cut and struck outwardly therefrom a bail orloop forming a latch receiving keeper 9 adapted to be received by and topass through the slot 8 in one part of the shank 5 of the key after thelatter has been inserted into the lock and the slotted part of the shank5 has been folded downwardly and inwardly into juxtaposition withrelation to the escutcheon plate A so that the said key can be fastenedin the lock in a manner presently described.

Pivotally mounted in the slotted part of the shank 5 of the key is ahook-like latch 10, the bill of which is adapted to engage in the keeper9 when projected through the slot 8 in the swinging part of the shank 5of the key so that the said key will be locked when inserted in thelock.

From the foregoing description, taken in connection with theaccompanying drawing, the construction of the device will be clearlyunderstood, and therefore a more extended explanation has been omitted.

What is claimed is The combination with an escutcheon plate having akey-hole and a strip cut and struck outwardly therefrom at a pointspaced from locking the section against movement to- L( the key-hole toprovide a keeper eye, of a Ward or away from the key-hole.
